.AZIMPROYVEMENT IN ORE-JIGGEIRS.

Specification forming part of Letters Patent No. [9 1.060. dated August 14, 1877; application filed A September 21, 1876. v r K To all whom it may concern.-

Be it known that l, SEBASTIAN STUTz, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented new and useful Improvements in Ore Washing and Separating Machinery; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being bad to the accompanying drawings, forming part of this specification, in which- 7 Figure 1 represents a vertical section taken at w wof Fig. 3. Fig. 2 represents'a back view, with a part of the pump in section. Fig. 3 represents a top "iew, with a horizontal section through the pump. Figs. 4 and 5 refer to a separator with a single sieve only, the

former being a vertical section through the pump and box, and the latter a top view.

The general combination and arrangement of the machinery difiersfrom thelone shown in the application filed by me on the 11th day of April, 1876, in the Patent Office, in the following particulars: 1 E

First, the plunger-box, with the mechanism imparting action to the water, is taken away, and a direct-acting steam-pump-of a particular construction is adapted to the separatorthe sieves receiving the layer of material to be separated, whereas these sieves in the above application have a fixed position.-

Third, the rotary valve, by which the outlet of stones, &c., was effected, has been replaced by a slide-valve, moved by means of pinions and racks. a

Fourth, the curved partition or pallet directing the water against the sieve, which has a fixed position in my application of April 11, 1876, is, in this, made movable.

Fifth, the outlet of the mud from the bottom of the washing-box is efiected automatically.

The above-mentioned direct-acting steampump is fixed to one of the sides of the separator-box A. The pump-cylinder'G may be provided with either one or two dischargingopenings, D, according to the number of sieves of the separator. E is the suction-pipe, and

P the piston of the pump. The latter, as represented in the drawing, is at the upper end of its stroke, and the valves '0 o of the suction-pipe are opened to allow the. inletoll' the water while; the discharging-valves d d. are closed.

Both sets of valves can at any time be easily examined and removed, if necessary.

A center piece, Gr, partly open at the front and back, to allow the necessary packing of the stuffing-box o and the water-cylinder pisa ton, Separates the water-cylinder 0 from the steam-cylinder F. By means of the pistonrod R, common to both, the movement is transmitted from the steam cylinderl to the pump.

The inlet and outlet of the steam into the cylinder is regulatedthrougha cylindrical valve, V, by means of the levers a a v a and the rods YT. 1 Instead of therotary valve, any other kind of valve may be used. 7

At. the upper end. of the piston-rod R is fixed a cross-head, H, which holds on itsextremities the rods 9 g. To the former, or g, two drivers,c e, are secured, by which the levers a a are alternately pushed up or down, in order to let the steam below or above the piston. Second, a vertical reciprocating movement is automatically/imparted to the rear end of The reciprocating vertical movement of the rear of the sieve S is obtained'by the rod 9, fixed to the other end of the cross-piece H, and acting through the shaft f, the .leverl fixed thereon, the cams h h, also fixed on the shaftf, andtherods i 11, by. which the Sieve is suspended. The rod 9" is provided with a slot, k, in which the lever'l is engaged. Each upward movement of the piston, and, consequently, of the rod g, raises also the lever l, as shownin Fig. 1, the result of this being that theshaft f is rocked to the same angle as the lever l, and with it the cams h h. The

latter are engaged into the guide-pieces m m,

fixed atthe end of the rods 13 0', so that, by moving the lever l upward, the rear of the sieve S will also be lifted up to the desired height-say from 2 to z. The front end of the sieve S is pivoted, and the dropping down of the rear is efl'ected by the weight of the material to be separated, and by the slot k in the return stroke.

Two other levers, o 0 are fixed upon the shaft f, corresponding to similar levers o 0 keyed to the 'blocks of the, stop-cocks K K. Both pairs of levers, 0 o and 0 0 are con nected by means of the rods 1) 10.- Thus, it will beseen that, through the rotary movement of the shaft f, the outlet of the mud from the lower part A of the separator-box is effected automatically, and in a most satisfactory way. 4

The curvedpartition or pallet N is suspended on hinges at its lower end, near the inlet of the clean water, and can be placed in different positions. By moving back the lever. I, which is fixed to the end of the shaft L, into the position 1 2, the little lever I, fixed upon the same shaft L, will take the position 2 3, which brings the edge of the pallet N closer to the sieve S. The current of the water is ,&c., are allowed to escape, is moved up and ."downvby means of the hand-wheel. Q, the pinions q g on the shaft of these hand'wheels, and the corresponding racks 88 on the gate. The material to be separated, being brought upon the sieve S at the back end, is moved forward by the action of the water to the front, and the lighter parts are drawn over the edge'U into the channel as, where they can slide down on an inclined plane to the buckets, whilethe heavier-material is let, from timeto time, intothe channel to, from which it passes down to the outside by another inclined plane.

-To obtain a completeseparation of the ma- -terial the up-and-down movements of the pump have to be of different speed. This I obtain by allowing only a small quantity of steam to go below the piston, so that the sucfor. the inlet of steam above the piston is so arranged that the pressure of'the steam will act suddenly.

In regardto the utility. of the invention I have to state that, bythe arrangement of the steam-pump in direct connection with the washing-box, the box of the plungers,jwith its mechanism, will be economical inoperation, and thus a great saving of expense effected. The lifting up of the sieve at the rear end, and the changes of the current of the water, will separate a much greater quantity of material thanhas heretofore been done. The automatic cleaning out of the separatorbox is alsoa saving of considerable time and money. I claim as my invention- 1. In a machine for separating or washing coal. the combination, with the separator-box and one or more sieves, of a water-cylinder, O, and a steam-pump mounted thereon, substantially as described. v

2. In a machine for separating and washing coaland other substances, the combination of a steam-pump, having a slow upward and sudden downward movement of the piston, with the valved connecting water-passag'es and the separator box or boxes, provided with one or more sieves, substantially as described. I

3. In a coal-washing machine, thecol'nbination of the separator-box, thepiston by which the water is driven, the passages leading from the piston-chamber to the box heneath the sieve, and a sieve hinged at one end and made to vibrate, as set forth. I

4. In combination with the vibrating sieve, the rods 4; 2', guides at m, cams h.h on shaft f, rocked-by arm Z and rod g,as set forth.

5. In combination with the sieve S, and arranged in proper relation thereto and to the passage D, the movable pallet N, as set forth. 6. The pallet N, hinged nearthe passage D, in combination with the shaft L and levers connected therewith, whereby t'he position of said pallet may be changed, as set forth.

7. The automatically-moved cock K, in combination with the rod 1) and shaft f, as set forth.

8. The described separator, consisting of the two chambers or boxes, the vibrating sieves, the adjustable pallets, the steam-pump, with cylindrical valves, the water-supply pipe, and the induction-passages D D, the several parts being relatively arranged substantially as and for the purpose specified.
